Some myths and realities of NGN – NGN simply means adoption of Internet protocol – There is lot more to NGN then just IP, ultimately it should result in increased revenues and reduced Capex and Opex – Massive turn key tenders ensure interoperability – Separation of Core from Access will help operator to simplify network and focus on convergence, operator has to ensure that standards will take care of interoperability – Technology and market will take care of NGN automatically – Strict adoption of NGN architecture and specific migration plan alone will help operator to reap the real economic benefits of NGN 13-Oct-2010

Some myths and realities of NGN – Service Provider can leverage on the expertise of vendor insofar as standards and interoperability are concerned by spelling out deliverables – To understand the deliverables, there is no escape for Service Provider from being technically fully informed – There cannot be any synchronization in IP – Sync Ethernet standards for IP have matured, Synchronous Ethernet, defined in ITU-T G.8261, provides SDH-grade timing over lower cost 1GE and 10GE interfaces. – Ethernet technology has not matured – The world and our competitors are already into fully interoperable MPLS compliant Carrier Ethernet with RPR support (equivalent of TDM SDH), All the leading vendors are supporting this technology on their Carrier Ethernet platforms, and the last EANTC MPLS World Congress event held in February 2010 demonstrated the strong momentum behind this technology, as well as multi-vendor interoperability 13-Oct-2010
